UNITED STATES PATENT rricnt JAMES A. XVHITING, OF BALTIMORE, MARYLAND.

SHlPS WINDLASS.

SPECIFICATION forming part of Letters Patent No. 304,152, dated August26, 1884.

Application filed April-9, 1884. (No model.)

To all whom it may concern.-

Be it known that I, James A.- 'VVHITING, a citizen of the United States,residing at Baltimore, State of Maryland, have invented cer tain new anduseful Improvements in Ships? \Vincllasses, of which the following is aspecification,

My invention relates to certain improvements in ships windlasses, whichwill be described, and then claimed.

In the accompanying drawings, Figure l is an elevation of the Windlass.Fig. 2- is a View showing the recessed head of the concave windjug-drum.Fig. 3 is a view showing the recessed head of the winding-drum and thelever with its hook-pawl rotating the said (1 rum.

The letter A designates the concaved wind ing-drum; B, the horizontalshaft on which it is mounted, as shown on the same shaft; G, the checksor standards on which are the bearings (Z for shaft. The concavewinding-drum has on the perimeter of its largest head ratchet-tecth c,with which a dr0p-pawl,f, engages to prevent backward rotation. A lever,G, has near its end a round hole, h, which takes about the horizontalshaft B, and thereby it'is pivoted on the said shaft close to the end ofthe drum. This lever also has a flange, 2', which straddles or takes onthe inner side 6 of the ratchet-teeth rim, and the lever has asocket,is, for the insertion of a hand-spike, L.

The foregoing parts are ofordinary construction; and my improvementconsists in recessing a small ratchet-wheel, n, in the end of the largehead, which adjoins the standard, and providing an annular space orrecess, 1), around the outside of said small wheel. To work inconnection with this small ratchet-wheel, a hook-pawl, q, is pivoted bya pin, 0', on the side of the lever G, near its pivot-hole h. It will beseen the hook-pawl projects from the side of the lever and occupies thespace or recessp, in the end of the large head, and its hook engageswith the small ratchet-wheel. The advantage of this construction is thatthe lever G is more effective because its hookpawl takes hold close tothe axis of the wind ing-druin, and at the same time as this is effectedby recessing the small ratchet-wheel in that end of the drum which isnext to the stand ard, and, providing an annular space for thehook-pawl, the device requires less room and does not add to the cost.

It will be seen the small ratchet-wheel n on which the lever-pawl actsis at the same end of the windlassdrum as the ratchet c, on which thedrop-pawl acts. By this construction room is economized.

I do not claim to have in vented a recessed Windlass-drum with a ratchettherein, but claim only the construction and arrangement of parts, ashereinafter stated.

Having described my invention, I claim and desire to secure by LettersPatent- The hereiirdescribed windlass, consisting of the standard G,horizontal shaft B, Wllldl2l$5- drums having, on the perimeter nearestthe said standard, ratchet-teeth e, and a pawl, f, pivoted on thestandard, engaging with said teeth, a recess in the drum-head next tothe standard, a small ratchet-wheel, n, on the shaft within the recess,with'an annular space, 12, around the outside of said smallratchet-wheel, and a lever, G, pivoted on the shaft between the drum andstandard, and provided with a pawl which occupies the annular space, asset forth.

In testimony whereof I affix my signature in presence of two witnesses.
